The door body 20 includes a front wall 22 away from the containing chamber S and is always sandwiched on the front wall 22 There is a side wall 23 between the front wall 22 and the side wall 23 between the accommodating chamber S and the side wall 24.

Here, the outer side 12 is the left side (corresponding to the left pivoting side P1) or the right side (corresponding to the right pivoting side P2) of the box 10, and different pivoting sides P correspond to different outer sides 12. The front wall 22 is the front surface of the door body 20, and the side wall 23 is the side surface of the door body 20.

15 and 16, when the door 20 is in the closed state, the first shaft 311 is located at the initial position A1, the second shaft 312 is located on the side of the first section L1 away from the second section L2, and the protrusion 21 is limited to In the groove 11.

Specifically, the bump 21 is limited to the groove 11 so that the vertical beam 40 extends to the second door body 202, that is, the vertical beam 40 will be attached to the inner surfaces of the first door body 201 and the second door body 202 at this time. , To prevent the cold air in the accommodating chamber S from leaking to the outside of the refrigerator 100.

In addition, the outer side surface 12 and the side wall 23 are located on the same plane, which can ensure the smoothness of the appearance, improve the aesthetics, and also facilitate the installation of the door body 20, but not limited to this.

17 and 18, when the door 20 is in the process of opening from the closed state to the first opening angle α1, the first shaft body 311 is maintained at the initial position A1, and the second shaft body 312 takes the first shaft body 311 as The center of the circle moves in the first section L1. At this time, the door body 20 rotates in situ relative to the box body 10 so that the protrusion 21 is separated from the groove 11.

Specifically, the protrusion 21 gradually escapes from the groove 11 through the notch 111, and at the same time, the vertical beam 40 rotates toward the side close to the receiving chamber S so that the first door 201 and the vertical beam 40 have a first folding angle β.

Here, when the protrusion 21 is completely separated from the groove 11, the first folding angle β is preferably kept less than 90 degrees to prevent the vertical beam 40 from affecting the opening and closing of the second door 202.

It should be noted that, since the protrusion 21 and the groove 11 are in an arc shape, when the door 20 is in the closed state, in the first direction X or the second direction Y, the protrusion 21 and the groove 11 are mutually Limiting, if the door 20 is displaced in the first direction X or the second direction Y when the door 20 is opened to the first opening angle α1, the protrusion 21 and the groove 11 will interfere with each other It jams and causes the bump 21 to be unable to escape from the groove 11, thereby causing the door 20 to be unable to open.

In this embodiment, when the door body 20 is opened to the first opening angle α1, the door body 20 rotates in situ relative to the box body 10 to ensure that the door body 20 does not move along the first direction X or the second direction Y during this process. , Thereby ensuring that the bump 21 can smoothly escape from the groove 11.

Here, the first opening angle is not greater than 10°, that is to say, approximately when the door body 20 is opened to 10°, the protrusion 21 may not be restricted by the groove 11, at this time, it may be the protrusion 21 It is completely separated from the groove 11, or the bump 21 will not interfere with the groove 11 even if it is displaced in the first direction X or the second direction Y.

In addition, if the outer side surface 12 and the side wall 23 are on the same plane when the door body 20 is in the closed state, the side edge 24 will protrude from the outer side surface 12 in the second direction Y during the rotation process (the protruding distance generally does not exceed 3mm).

19 and 20, when the door 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the second shaft 312 moves in the second section L2 to drive the first shaft 311 Move from the initial position A1 to the first stop position A2.
